Pigs are one of Anna’s passions. When people love pigs, in my opinion, they are special and unique — and in my opinion, the chosen ones — because they’re just such a special animal, highly intelligent, emotional animal, so it’s like working with orphans.

All which raises the question, who exactly is Gristina? Is she the 44-year-old, suburban mother of four? A brothel queen bee with nude model ambitions? Or is she simply a misunderstood swine lover?

DNAinfo tracked Walker down, and he said he was shocked to hear the allegations: “I’m surprised at having to answer these questions,” he said. “She was the mom next door.”

While Walker has not been officially charged with any crime, he is believed to have been interested in financially advising and supporting Gristina in an online prostitution venture. Prosecutors said, “We picked her up yesterday with a Morgan Stanley banker who she counts a close friend and she had been present at his office for a meeting in which she was trying to solicit money to fund what we believe is another business venture on the internet that involves matching up male clients with female prostitutes.”

But the defense is arguing that Gristina’s “business” and subsequent meeting with David Walker were part of her plan to launch a legitimate online dating site she believed could rival Match.com and similar services.
